VENTUS TR Black VeloCore+ and Diamana WB are both positioned as low-launch, low-spin wood shafts, but they are not interchangeable builds. Compare suitable weight and flex options in the same head before choosing between their profiles or installed prices.

Match the actual weights, not the labels
The Fujikura specification lists TR Black+ 6 S at 69 grams, while the Mitsubishi table lists WB 73 S at 70 grams. Both are raw 46-inch specifications. WB 63 S is listed at 62 grams, so the similar-looking “6” and “63” labels do not produce the closest weight match in this example.
| Option | Published raw weight | Published raw length |
|---|---|---|
| VENTUS TR Black VeloCore+ 6 S | 69g | 46 inches |
| Diamana WB 73 S | 70g | 46 inches |
| Diamana WB 63 S | 62g | 46 inches |
This is not a prescription to choose stiff flex or either weight. It illustrates why the fitter should select comparable actual options. Trimming, grip, adapter and head contribute to the finished club.
Low spin is a design position, not the objective for everyone
Start with your current driver and a clear flight question. If your useful carry already depends on modest launch and spin, reducing either further may be unhelpful. Do not choose a low-low profile because it appears associated with stronger players.
The manufacturer descriptions make these candidates worth investigating for a suitable fitting question. They do not establish how much either shaft will change your numbers. We have not tested the two builds and do not claim a distance or dispersion winner.
Keep the head and setup controlled
Use the same driver head, loft setting and target playing length for the initial comparison. Record the actual shaft versions: original TR Black and current VeloCore+ are different generations. If an older demonstrator is used, identify that before ordering a newer version.
Our shaft-weight guide explains weight terminology. The playing-length guide helps make the test and final order comparable. A small difference in the final assembly should be recorded rather than hidden behind the same shaft family name.
Compare the shots you need on the course
Alternate short groups toward the same target and keep typical misses in the record. Examine strike location, carry range, start direction and the shape of the dispersion. A low-spin best shot that leaves you with less predictable ordinary drives is not an obvious improvement.
Include feel as personal feedback. Describe what you sense during the transition and through impact, but avoid treating “stable” or “smooth” as objective scores. If you cannot distinguish the results reliably, a second short session may be more useful than choosing the more expensive option.
Request two complete US build quotes
Each quote should identify shaft generation, weight, flex, adapter, grip, tipping instructions, finished playing length and final checks. Ask whether any existing components will be reused. Compare the delivered total rather than a shaft-only advertisement with an installed assembly.
Confirm the seller’s current stock and lead time for the exact option. A similarly named replacement may not reproduce the fitting. If one component is unavailable, decide whether to wait or retest rather than accepting a substitute by default.
Choose only after the specification is clear
Keep your current shaft in the decision until one of the new builds demonstrates a useful advantage. Price matters, but first establish that both quotes describe the builds you actually evaluated.
